SFECIFICATION forming part of Letters Patent No. 588,390, dated August `17', 189'?.

I Application led March 26, 1897 Serial No. 629,424. (No model.)

Be it known that I, GEORGE G. F. BOSWELL,

of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Adjustable Curtain; and l do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like figures refer to like parts.

The chief obj ect of this invention is to provide ready and attractive means for closing openings, especially doorless openings, of varyin g dimensions between rooms in houses.

This is desirable to prevent dust while sweep-v curtains, paintings, or other things while a` room is being swept or cleaned or at any other time or for any other purpose.

The full nature of-my invention will appear from the accompanying drawings and the description and claims following.

In the drawings, Figure 1 represents the curtain in placeovera square opening. Fig. 2 is a longitudinal section of the upper curtain-pole and curtain, the right-hand end of the pole, however, not being in section. Fig. 3 is a section of the right-hand endof the pole shown in Fig. 2 without the curtain or wire. Fig. 4 is a detailed view of the connection .between the side and top Vpoiles and their attachment to the casing. Fi g.v 5 is a plan view of the part shown in Fig. 4.' Fig. 6 is an elevation of the upper portion of a side pole, the same being broken away, as shown. Fig. 7

l shows the means for attaching the curtain to an arched opening.. v

Indetail, 1 is the casing of an opening between two rooms in a house. The curtain attachment comprises three telescopin g poles, one above and one on each side. The side poles are hinged or otherwise joined to the endsl of the upper pole, as will hereinafter be Incidental to the chief object above shown. On these polesthe curtain 2 is placed by .providing along its upper and side edges a casing large enough to slip the poles through. y The curtain is, when stretched, large enough to cover the largest opening thatrmayprobably be desired, and the poles are likewise so constructed` as to be long enough to provide for the covering of such large opening. The covering of smaller openings is accomplished by contracting the length of the poles which causes the curtain to gather on the poles. This permits the height or width or both to be adjusted. t

The poles adopted are telescoping. The upper one shown is composed of three telescoping tubular sections 43, 4, and 5, respectively. The tube 4 is smaller than the tube 3 and slides init, while the tube 5 is smaller than the tube 4 and slides in it. The outer end of the tube 5 is enlarged at 6. Then the whole upper pole is surrounded by a spiral wire 7, extending vfrom one end to the other. -The diameter of this spiral wire is such as to permit it being easily slipped over the larger section 3. The casing of. the curtain 2 surrounds the spiral wire 7 and is secured to it by threads or cords 8, that loop under each coil of the wire. The purpose of this is to secure the curtain to the wire and to cause it to move with the wire when lthe latter is contracted or expanded, and this will cause the curtain to be equably distributed land lprevent its collecting in bunches when the upper pole is le'ngthened or shortened. The larger tube 3 of the .upper pole has in its outer end a block or plug 9, and the other tubes 4 and 5 are likewise provided with such a plug, to which a cord or rope 10 is secured. The

purpose of this cord or rope is to limit the telescoping movement of the sections, so that they cannot-escape from eachother, and yet it permits such tubes to be moved freely one inthe other for nearly their whole length.

tube 11 and is secured at the other end to the tube 12, so that the'tendency of such in a vertical position against the wall.

spring is to lengthen such pole, and when the upper pole is secured to the casing or made stationary it always forces the lower section 11 of the side pole down on the fioor. The lower section 11 may have a spike in the lower end to enter the iioor or not, as desired. The spring 13 has also the additional function of holding the curtain material away from the end of the tube 11 when the side poles are shortened, so as to prevent such material from being cut or injured.

The side poles are secured to the ends of t-he upper poles preferably by hinging. The means shown consist of the section 14 of the hinge being secured to the end of the upper pole and the other section 15 secured to the upper ,end of the side pole. The two sections are pivoted at 16.

This attachment is secured to the casing preferably in the following ways: If an `opening be square, I place at each upper .cornerof the casing a bracket 1.7, that lhasa horizontal lug 18, extending toward the .opposite corner to receive the end ,of the upper curtain-pole and another lug 19, that extends downward :to receive 4the upperend of thes'ide .curtain-pole. The attachment is placed on these two brackets in the following manner: The upper pole is shortened and the two ends placed .over the two lugs 18. Then first one side pole ,and then the other is held in the iirst place in a folded position, as shown in dotted lines in Fig. 4, and in such position that its upper end will pass or extend over the lug 19 when the pole is moved downward into a vertical position, as shown in said Fig. 4. The side poles at their lower vends are placed yon the floor close against the casing, so that the whole opening is tightlyclosed. If, however, an arched opening is desired to .be covered, I use ya hook 20, centrally located-on the arch. Over this I .centrally place the upper pole .of the curtain and then place the two side poles The one hook 2O will `thus hold the whole curtain structure in place.

The curtain is caught upon the side poles by the .clamps 21, that are placed about the curtain and the upper end .of the lower section 11 of the side poles, as shown in Fig. 1.

These are so placed that from them the curtain will hang gracefully to the floor, but above them itwill gather as it is compressed or extended, but thc curtain is made of such dimensions that it cannot extend so far upward as to permit the smaller section 12 of the side poles from escaping out of the larger lower sections 11.

In this description it is seen that the curtain can be adapted to openings of different sizes and forms and will cover them completely, that it is readily put in place or removed, and when removed can be put into a bundle of very small dimensions, as both side poles can be folded against the upper pole.

lVhat I claim as my invention, and desire to secure by Letters Patent, is-

1. An adjustable curtaincomprising an upper horizontal pole, consisting kof tclescoping tubes with la wire coiled about them of a diameter as great as the outside tube, avertical telescoping pole secured to each end of the upper pole, and sucient 4curtain material secured to said poles to permit enlargement .or diminution of the curtain.

2. The combination with the casing of an opening .or object to be covered,of an adj ust- .able ,curtain ,compr-isin g an .upper horizontal telescoping Pole, a vertical telescoping pole hinged to each end of the zupper .pole and suiiicient .curtain material secured to said poles to permit appropriate adjustment of size,and means for detachably securing said poles to the casing.

3. The combination with a casing of an opening or object to be-covered, of lanadjustable curtain .comprising a tubular telescoping horizontal pole, a vertical pole hinged at each `end of the horizontal pole, a bracket se cured'to the ycasing at each end of the horizontal pole and having a lug rextending horizontally inward .to receive the horizontal pole and another lug extending .downward to receive the ends of .the vertical pole, and suitable curtain .material secured to such poles, substantially as set forth.

In witness whereof I have hereunto set my hand this 18th day .of March, 1897,

GEORGE G. F. BOSWELL.
